This option enables the FCKeditor HTML WYSIWYG editor in all areas where there is an option to edit HTML content within your CakeMail user interface. The FCKeditor makes it easy for end-users to modify, personalize and add links to their HTML, and preview their content before sending a mailing.
FCKeditor is an HTML WYSIWYG editor control by Frederico Caldeira Knabben, the creator of the editor (also what FCK in FCKeditor stands for). Due to the coincidental and unfortunate vulgarity of his initials, the program's name will be changed to CKEditor with v3.0. FCKeditor is compatible with most Internet browsers, including: Internet Explorer 5.5+ (Windows), Firefox 1.0+, Safari 3.0+, Google Chrome, Opera 9.50+, Mozilla 1.3+ and Netscape 7+.
